Description

Sampling swab with culture medium

Technical Field

The application relates to the technical field of medical appliances, in particular to a sampling swab with a culture medium.

Background

In the current nucleic acid detection methods, it is generally necessary to prepare a swab and a test tube embedded with a pre-prepared medium in advance. The operator inserts the sampling head of the swab into the nasal cavity or throat of the subject to collect the sample. The collected swab is then placed in a test tube, ensuring that the sampling head is in sufficient contact with the pre-prepared medium in the test tube. The stem of the swab is then broken off so that the remainder of the swab can be placed completely in the tube, which is then sealed tightly to preserve the sample for subsequent testing.

However, in the existing nucleic acid detection methods, the different instruments to be detected are separate, and the swab and tube with the pre-formed culture medium embedded are two separate instruments, rather than an integrated design. Because of this separability, the operator needs to handle the swab and tube separately, increasing the number of steps and complexity of the operation. Especially in the case of a large number of detected persons, such a split design is more likely to cause an operation error. Such errors may include incorrect sample pairing, under sampling or unsealed test tubes, and the like, thereby affecting the accuracy of the test.

Therefore, it is necessary to provide a sampling swab with a culture medium, so that each instrument is not dispersed any more, so as to simplify the operation flow, reduce the operation steps, and improve the efficiency and accuracy of the detection process.

Referring to fig. 1 to 6, in an embodiment, a sampling swab with a culture medium includes a casing 100, a sampling assembly 200, and a drip cover 300, wherein a pipe 110 and a first pipe orifice 120 communicating with the pipe 110 are provided in the casing 100; the sampling assembly 200 may extend into the conduit 110 through the first nozzle 120 and be coupled to the cannula 100, and the culture medium within the sampling assembly 200 may flow into the conduit 110 through the first nozzle 120. Specifically, the inside of the sleeve 100 is provided with a pipe 110 connected to the outside through a first nozzle 120. The sampling assembly 200 may extend into the pipe 110 through the first nozzle 120 and be connected to the sleeve 100, and the sampling assembly 200 may have a culture medium disposed therein, which is in a liquid state and may flow into the pipe 110 through the first nozzle 120. The integrated design can detachably connect the sampling assembly 200 and the pipeline 110 together, so that the operation flow is greatly simplified, and the occurrence of human misoperation is reduced.

It will be appreciated that in conventional methods, the swab 220 and the tube with the pre-formed culture medium are two separate devices, and the operator is required to perform multiple steps, such as pairing the swab 220 and the tube, placing the swab 220 in the tube, etc., and such a separate design is prone to operator error. In the present application, the sleeve 100 and the sampling assembly 200 are designed to be integrally and detachably connected, the operation steps are reduced to the minimum, and the sampling and storage can be completed only by extending the sampling assembly 200 after collecting the sample into the pipeline 110 through the first pipe orifice 120 and connecting the sampling assembly 200 with the sleeve 100, and the culture medium in the sampling assembly 200 flows into the pipeline 110 through the first pipe orifice 120.

Referring to fig. 3 to 5, in an embodiment, the sampling assembly 200 includes a cap 210, a swab 220, and a flask 230, wherein the cap 210 is insertable into the first nozzle 120, and a connection hole 212 is formed in the cap 210; one end of the swab 220 is connected with the tube cover 210, and the other end of the swab can extend into the pipeline 110 through the first tube opening 120; the culture flask 230 is disposed at one end of the tube cover 210 away from the swab 220, a storage room 231 for storing culture medium is disposed in the culture flask 230, and the storage room 231 is communicated with the pipeline 110 through the connection hole 212. Specifically, the main function of the tube cap 210 is to connect the swab 220 and the flask 230, ensuring that the medium can smoothly flow into the tube 110; the main function of the swab 220 is to collect a sample and extend into the tubing 110 through the first nozzle 120 to contact the medium inside. The design of the swab 220 ensures the accuracy and effectiveness of the sampling; the inside of the flask 230 is provided with a storage space 231 for storing a pre-prepared culture medium, and the storage space 231 is communicated with the pipe 110 through the connection hole 212, so that the culture medium can be ensured to smoothly flow into the pipe 110. The design of the sampling assembly 200 allows the cap 210, swab 220 and flask 230 to be tightly coupled to form a compact unit. This integrated design ensures coordinated operation of the various components so that the process of swab 220 collection, media storage, and sample introduction into tubing 110 is seamless, without requiring the operator to handle multiple discrete components in different steps. This reduces the possibility of misoperation, ensures the accuracy of each step, and improves the reliability of detection.

Referring to fig. 2 to 4, in one embodiment, the culture flask 230 is made of a deformable material, and the culture flask 230 is pressed to squeeze the culture medium in the reservoir 231 into the casing 100. Specifically, the culture flask 230 is made of a deformable plastic material, and has a certain extrudability. The culture flask 230 made of the material has good plasticity, and can be extruded according to the requirement, so that the culture medium in the storage room 231 can be extruded smoothly.

Specifically, the central axes of the first nozzle 120 and the second nozzle 130 are the same, ensuring that the swab 220 is not skewed or misplaced during the connection process, ensuring even distribution and accurate sampling of the culture medium. The second nozzle 130 may be used to discharge the medium, and the drip cover 300 may be connected to the sleeve 100 and shield the second nozzle 130 from the medium discharge in the pipe 110. When the drip cover 300 is connected to the cannula 100, the sampling swab 220 is placed upright such that the natural flow of culture medium is placed in the conduit 110 within the cannula 100, resting adjacent to the second nozzle 130. The culture medium is ensured to be fully contacted with the sampling area near the second pipe orifice 130, the contact area of the culture medium and the sampling head 221 is increased, namely, the contact area of the culture medium and a sample is increased, and the culture effect and the culture accuracy are ensured. When it is desired to use the collected sample, the operator can separate the drip cover 300 from the cannula 100 so that the culture medium in the cannula 100 flows outside through the second nozzle 130.
